Cobray Terminator 12ga Shotgun

The Cobray Terminator is an unusual - and unusually impractical - single-shot 12 gauge shotgun. It uses a sort of open bolt system in which the barrel is under spring pressure, and slams backwards into a fixed firing pin when the trigger is pulled. Only about 1500 of these were made before they were discontinued due to poor sales (not because of ATF intervention, as some people believe).
